IntelliJ platform (JetBrains IDEs) has this functionality out of the box without "AI" using regular code intelligence. If all your parameters are strings it may not work well I guess but if you're using types it works quite well IME.
Can't use JetBrains products at work. I also unfortunately do most of my coding at work in Python, which I think can confound things since not everything is typed
... you can't use JetBrains? What logic created a scenario where you can't use arguably the best range of cross platform IDEs, but you can somehow use spicy autocomplete to imitate some of their functionality, poorly?
